I'd like to recommend the following article by Clark Pinnock. It is called, "Climbing Out of a Swamp: The Evangelical Struggle to Understand the Creation Texts" [Interpretation 43 (1989) 143-155]
Pinnock argues convincingly (to me, anyway) for the importance of reading the Creation texts as they stand, in their ancient and authorial context first and foremost. In the end, he comes out at the position to which I have come, and I will therefore use the points made in this article when I make my case for a literary framework interpretation of Genesis 1.
He does not go far enough, however, in relating these texts to their literary context in the Torah and the Sitz im Lieben of Moses and the Israelites. I realize this may be beyond his purpose in the article, nevertheless, grasping this is essential for truly understanding the purpose and meaning of the text, and therefore arguing against those who would hijack it for other agendas, such as trying to prove a particular scientific viewpoint.
